Check the Health of Global Managers and Regional Managers

Do one of the following to check the health of the Global Network Management feature:

Log on to the Global Manager as an NNMi administrator, and open the NNMi console on the Global Manager (NNMi management server). Click here for more information.
1. Click the Help → System Information.
2. Click the Global Network Management tab.
3. In the Regional Managers Reporting to this Global Manager section, review the list of all Regional Managers that report to this Global Manager:
  - Name: The current value of the Name attribute for this Regional NNMi management server (as specified in the Remote Manager Connection form).
  - Connection State: The current state of communication between the Global Manager and Regional Manager. There are four possible values:
    
    Not Established — A new Regional Manager Connection is not yet fully functional. This state is brief unless NNMi encounters a problem.
    
    Connected — Data is flowing between the Global Manager and the Remote Manager.
    
    Not connected — A previously established connection is no longer working. See Clock Synchronization Issues (SSO / Global Network Management).
    
    All NNMi management servers in your network environment that participate in Global Network Management (Global Managers and Regional Managers) or Single Sign-On (SSO) must have their internal time clocks synchronized in universal time.
    
    Caution Use a Time Synchronization program, for example, the Linux tool Network Time Protocol Daemon (NTPD) or one of the available Windows operating system tools.
  - Node Count: The number of nodes in the Global Manager's database that are being managed by this Regional Manager.
Log on to the Regional Manager as an NNMi administrator, and open the NNMi console on the Regional Manager (NNMi management server).Click here for more information.
1. Click the Help → System Information.
2. Click the Global Network Management tab.
3. Scroll down to the Reporting to Global Managers section, and review the list of all Global Managers that receive data from this Regional Manager:
  - Name: The fully-qualified DNS hostname of the Global Manager (NNMi management server).
    
    Note If you see something other than a fully-qualified DNS hostname in the Name column, the Global Manager is down and has been down since this Regional Manager was last restarted (see Stop or Start an NNMi Process or Stop or Start NNMi Services for more information).
  - Messages Currently in Queue: The current number of messages that need to be sent to the Global Manager.
    
    Messages are automatically sent to the Global Manager. If the number of messages in the queue continually increases and never decreases, or if the number of messages in the queue consistently exceeds 10,000, then there might be a problem.
    
    Note If the Global Manager is down for maintenance for a few hours, the queue size naturally increases until the Global Manager is back online.
    
    Queue size over 100,000 indicates a serious issue. Consider disconnecting that global manager until the issue can be resolved.
NNMi administrators can use the command line on any NNMi management server to generate a report about NNMi health. See the nnmhealth.ovpl Reference Page for more information.

There are two ways to log on to a Regional Manager:

Directly log on to the Regional Manager (NNMi management server).
From the Global Manager, select any Node being managed by the Regional Manager and click Actions → Regional Manager Console. See Actions provided by NNMi.
